Copper Cathode was formed by making will blister (99% copper) a plank as positive pole, making pure copper a flake as negative pole, and then put the mixture of H2S04 and CuSO4 together as electrolytic. After making contact, copper was dissolved as Cu moved from positive pole to negative pole, when it arrives at negative pole, it will acquire electrons and then exploited pure copper ( named as Copper Cathode) there. Beijing Shengshi Hengfeng Trading Co., Ltd imports Copper Cathode for long time, the import quantity is about 2,000 tons per month, and the specific product description and specification are as follows:
